Frankstown Branch Juniata River

The Frankstown Branch Juniata River is a 46.0-mile-long (74.0 km)[1] tributary of the Juniata River in Blair and Huntingdon counties, Pennsylvania, in the United States.

[2] The headwater tributaries of the Frankstown Branch rise on the slopes of the Allegheny Front south of Altoona.

The Frankstown Branch forms at the village of Claysburg by the confluence of Beaverdam Creek and South Poplar Run, then flows north along the western base of Dunning Mountain.

Turning southeast at Point View, the river breaks through the mountain in a water gap and passes Williamsburg, then turns north again, now against the western base of Tussey Mountain.

The Warrior Ridge Dam and Hydroelectric Plant is located on the Frankstown Branch in Logan Township and Porter Township in Huntingdon County.
